Hi @abdulaziz.doro, Are you using any proxy in your environment for internet connectivity, or are you in an air-gapped environment? If so, this SSO login might not work. You will need to raise a TAC case to obtain the offline version of the Firewall Migration Tool.

This is a known issue with the ASA to FTD Migration Tool when it can’t properly authenticate or validate the CCO session.

Quick checks to resolve it:

Make sure you’re using a Cisco account with active Smart Licensing access.

Verify internet access and proxy settings (the tool often fails behind corporate proxies/firewalls).

Try running the tool as Administrator and disabling SSL inspection temporarily.

Confirm the FMC version matches the migration tool version (7.7 tool requires FMC 7.7).

If it still fails, download the tool again and clear any cached credentials.

If none of the above works, open a Cisco TAC case this issue is commonly server-side or account-related
